WINDOW-SHADE ATTACHIVI EN-T.

SPECIFICATION forming part of Letters Patent No. 630,170, dated August 1, 1899.

Application filed March 13, 1 899.

To all whom it may concern.-

Be it known that we, ALPHONZO F. BLAKE and EDWARD V. COX, citizens of the United States, residing at Coxs Landing, in the county of Oabell, State of WVest Virginia, have invented a new and useful Window-Shade Attachment and Adjustment, of which the following is a specification.

- This invention relates to window-shade hangers of that class having a vertical adjustment whereby ventilation and light may be admitted over the top of the shade, and has for its object to provide an improved frictional lock for adjustably holding the cord which supports the shade-roller and which is adapted to be released by operation of said supporting-cord, so as to permit of the vertical adjustment of the shade.

To these ends the present invention consists in the construction and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that changes in the form, proportion, size, and the minor details of construction may be made within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the present invention.

In the drawings, Figure 1 is an elevation of a portion of a window-frame having a shade fitted thereto by means of the present invention. Fig; 2 is an enlarged transverse sectional view illustrating the manner of mounting the shade-roller. Fig. 3 is an enlarged detail elevation of the cord-lockingi device. Fig. 4 is a detail elevation illustrating the manner of connecting the shade to the cord. Fig. 5 is a transverse sectional view taken on the line as it of Fig. 3.

Corresponding parts in the several figures of the drawings are designated by like characters of reference.

Referring to the accompanying drawings, 1 designates the window-frame, and 2 the window-shade, which is adj ustably mounted thereon. The shade is preferably of the spring-roller type and is mounted as best illustrated in Fig. 2. A suitable rod or pole 3 extends entirely across the window-frame Serial No. 708,950. (1\To model.)

and supports the spring-roller 4 by means of suit-able screw-eyes 5, detachably pendent from the opposite ends of the pole or rod and receiving the oppositejournals 6 of the springroller. The eye 5 (illustrated in Fig. 2) is angular in shape, so as to fixedly hold the spring-actuated journal of the curtain-roller, V

and it will be understood that the opposite eye is rounded or enlarged, so as to permit the turning therein of the roller -journal. Furthermore, as indicated in dotted lines, it will be seen that the shank of the eyes may extend at substantially right angles to the eyes proper, so that the same may be attached to the sides of the pole 3 instead of to the bottom thereof.

The shade 2 is provided with the usual cord -7, which is pendent from the lower edge of the curtain and adapted to operate the latter upon the roller and is also employed to sus pend the pole 3 by engagement with the improved cord-lock. As best illustrated in Fig. 3, it will be seen that the improved lock comprises an essentially T-shaped lever, having a transverse head 8 and a pendent releasingshank 9, the latter being provided at its lower end with an outwardly-projecting foot or extension 10, having a vertical opening 11 provided therethrough. One end of the head 8 is pivot-ed to an attaching-plate 12 by means of asuitable pivot-pin 13, it being understood that there are two plates 12, which form a casing or housing for the locking-lever. The opposite end of the head 8 is provided with a concaved toothed portion 14:, which is adapted to cooperate with a transverse shoulder 15, formed by a suitable pin or lug carried by the sides of the casing.

The cord 7 is adapted to be passed over the shoulder 15, as will be hereinafter explained, and then extends downwardly to the pole 3, with which it is connected in the manner shown in Fig. at. Fitted to the pole and located midway between the ends thereof is a collar 16, having an upwardly-projecting tapered and split sleeve 17, which is adapted to receive the end of the cord, and asubstantially conical binding-sleeve l8 is carried by the cord and firmly embraces the split sleeve 17, so as to tightly bind the same upon the end of the cord.

In the operation of the device it will be seen that the free end of the cord is passed upwardly between the toothed portion 14 of the locking-lever and the adjacent side of the shoulder 15, thence over the top of the latter,

downward across the inner side of the cord, and then loosely through the opening 11, formed in the foot 10. Thus it will be seen that the Weight of the curtain is sustained by the upright portion 19 of the cord, which-will bind between the toothed portion of the locking-lever and the adjacent side of the shoulder 15, so that the cord is prevented from accidentally slipping downward, and the shade is suspended in position. To release the locking-lever, it is simply necessary to pull downward upon the portion 20 of the cord which passes'loosely through the opening in the foot of the lever, and by reason of the lateral inclination of the portion :21'of the cord the shank 9 will be moved laterally into the position-indicated by dotted linesin Fig. 3, so that the toothed portion 14 Will be thrown out ofengagement with thecord, and thelatter is free to be moved,so as to adjust the height of the ,pole3. Immediately upon releasingtheportionBO of the cord the lockinglevcrwill return to its original position by means of vgravity and the cord will be again held, as hereinbefore described.

The present invention provides an exceedingly simple and useful device which will antomatically lock the cord immediatelyupon releasing-the latter and also permits of free movementof the cord when it is desired to adjust the height of the shade.

What we claim is The combination with a window-shade and a suspending-cord therefor, of a T-shaped locking device, the head of the latter being pivoted at one end, and its opposite free end being toothed, the releasing-shank thereof extending downwardly at substantially right angles to the head, and provided at its lower free end with a lateral foot having avertical opening formed therethrough, and a rounded shoulder arranged adjacent to the free end of the head and in the same horizontal plane withvthe pivot thereof, the suspending portion of the cord extending upward between the free end of the pivoted head and the shoulder, over the latter, thence inclined downwardly across theupright portion-of the cord, and finally downwardly and loosely through the opening in the footof the releasing-shank, whereby a straight downward pull upon the latter free portion of the-cord will throw the free foot end of the releasing-shank toward the shoulder, and thereby move the free end of the head out of engagement with the cord, substantially as and for the purpose set forth.

In testimony whereof we have signed our names to thisspecification, in the presence-of the two subscribing witnesses, this 27th day of February, 1899.
